Part B - RNA primers on the leading and lagging strands

The diagram below shows a replication bubble with synthesis of the leading and lagging strands on both sides of the bubble. The parental DNA is shown in dark blue, the newly synthesized DNA is light blue, and the RNA primers associated with each strand are red. The origin of replication is indicated by the black dots on the parental strands.

Rank the primers in the order they were produced. If two primers were produced at the same time, overlap them.

The primers are produced firstly to the area of the double strand DNA that was separated earlier.

Because DNA near a and h primers was separated first, these primers (a and h) were produced first. After that, the DNA near g and b was unfolded, so these primers (g and b) were produced next. Similarly, the next primers were f and c, and finally e and d.

primers are produced firstly to the area where the double strand DNA separates

The longest light blue arrow represents where DNA begins to separate, These primers are (a,h) are produced first. After that, the DNA near g and b was unfolded, so these primers (g and b) were produced next. Similarly, the next primers were f and c, and finally e and d.
 P.S on mastering biology overlap (a,h) (g,b) (f,c) and (e,d) in this order. these are both happening at the same time on both sides.
